This paper presents the design of a framework for the optimization of a low-power, low-noise, broadband transimpedance amplifier to be used in a fiber optic transceiver. The design is implemented using a 180 nm six-metal-layer digital CMOS process with a 1.8V supply. The performances achieved are a gain of (Formula presented.), a bandwidth of 2.21 GHz, an input referred current noise of (Formula presented.)pA/Hz1/2, and a power dissipation of 13.5 mW.
